Transverse momentum spectra of fermions and bosons produced in strong abelian fields

Abstract

We study the transverse momentum spectra of fermions and bosons produced in strong, time-dependent abelian field. The transverse size of the abelian field is finite, similarly to color strings and ropes. Different time-dependent field strengths are investigated in a kinetic model, and transverse momentum spectra are calculated for fermions and bosons. These spectra display exponential or polynomial behavior at high p_T, depending on the given time dependence. We compare our spectra to lattice result for a classical gluon field and obtain surprisingly good agreement in certain cases.
